General description
Dioxybenzone belongs to the class of organic UV filters, which find wide application in personal care products and food packaging materials. These filters are prevalently employed as active ingredients in sunscreen formulations due to their ability to emit and/or absorb UVA and UVB radiations. Owing to their ubiquitous use and discharge into the environment, they are identified as common environmental pollutants.
This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here
Application
Dioxybenzone may be used as an analytical standard for the determination of the analyte in animal samples, artificial seawater samples, fresh and saline waters by various chromatographic techniques.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
Other Notes
Ion Mobility: TWCCSN2 value of 149.3 Å2 [M+H]+, 166.1 Å2 [M+Na]+ and 151.1 Å2 [M-H]-
The collision cross section (CCS) measurement was provided by Waters Corporation, using the SYNAPT XS mass spectrometer.
